Referring reference c view of a mine car embodying the invention; Fig. 2 is a side elevational view of the same; Fic'. 3 is an enlarged end elevational view of'tlie same; Fig. 4 is an enlarged cross Asectional View of the same taken on the line 4 4 of Fig, 1, and Fig. 5 is an enlarged longitudinal sectional view taken on the line 5--5 of Fig. 1.

" Referring now in detail to the drawings,

the reference character 1 indicates the floor of the car, 2 the side walls and 3 the end walls. y

`The floor 1 comprises a horizontally disposed plate 4 which 'preferably extends in one piece from side to side and from end to end of the car. the car, angles 5 and 5 respectively are provided, one flange of each of which is disposed horizontally and is secured to the floor plate 4 while thel other flange is disposed vertically upward. Beneath the floor plate 4 and on each side of the transverse center line of the car, a 'transverse member 6 is provided- Awhich preferably extends' forthe full width of the car. bers is preferably of Z shape in cross Section,

i having a vertically disposed web 7 and top 3o and 'bottom horizontally disposed flanges 8 and 9 respectively. The top fiange 8extends inwardly Vin a direction toward the transverse center line of the car and contact with the underside of the floor plate 4, and is secured to the horizontally disposedl flanges of the angles 5, *The bottom flange 9 extends outwardly in a direction toward the end of the car and is spaced away from the floorplate 4 and forms a support for the lrear end of a buffer block 10. lAt each end of the car' and beneath the floor thereof spaced'longitudnal members 11 4are rovided which preferably extend outwardly from the member 6 to the end of'tlie car.

i `these members is preferably Z 'shaped 1n cross section liaving'a vertically f disposed web 12, a horizontally disposed out- Wardlyextending top flange 13 'which is secgrejd'to thefloor plate. 4, and ahorizontally 5 disposed inwardly' extending bottom `flange 14'which serves as an additional support for the buffer block 10;V The buffer' locks 1.()

, angle 5a are preferably made of wood andeach is secured to the floor. of the car, transverse member 6 and angle 5a by vertical bolts, and to the `webs 12 11 atone end of' the car by transverse bolts. The outer end portion of the block extends beyond the end of the car and is provided with a metallic buffer plate 15:'

Intermediate the transverse members 6 and adjacent each side of' the car the floor plate 4 is provided with an opening which preferably extends from the member 6 at one endV of the car to the member 6 at the opposite end of the car. Each of these openings is covered by a member 16 having an upwardly extending hood portion 17 having closed endsv and' horizontally disposed end and side Hanges 18 and 19 respectively which are preferably integral `with the hood portion 17 and with each other. The end flanges 18 are secured to the top flanges 8 of the transverse members 6 and the side ianges 19 are secured to the floor plate 4. Each of these members 16 when secured in this manner form a recess 20 for the reception of the upper portions of the wheels 21, at each side of the car, which are mounted on axles 22 suitably journaled in boxes 23' which are secured tothe floor plate 4, angle 5 and one Between the members 16 and at'substantially the longitudinal center line of the car a longitudinal member 24 is provided which preferably extends from the at one end of the car to the angle 5B at the opposite end. This member has horizontally disposed side and endf portions 25 and26 respectively Ywhich rest on the upper surface of the floor plate 4 and are secured to such plate and tothe transverse members 6 and buffer blocks 10.-4 Intermediate the side portions 25 this member is provided with an upwardly disposed yclorruga'tion 27 which preferably terminates short of the ends of the member. It will here be noted that the angles 5', transverse `members 6, hooded members 16 'and member 24 when or the floor which is pulling shocks to which a mine car is sub-v;

To strengthen the end wall, a coping iron 35 is provided which extends u:trom 4 side to side of the car ,and is secured at]y intervals throughout its length to the upper'edge portion ot the plate 322 To, strengthen the side wall a coping iron 36 is provided which extends romend to end of the car. This member is provided with an upstanding 37 which is secured at intervals throughout its length to tle upper portion of the side plate 33, a horizontally 'disposed web 38 and a downwardly and inwardly di- `the adjacent end wall 43.- Mounted inlfthe end within thev casing reeted outer flange 39. The web 38 adjacent the ends ofthe car is gradually reduced in depth as indicated by the. reference character 40 so that at the .end of the car there is only theA thickness of the metal from which the member is made projecting o11t`- wardly irom the side wall. It, will here be noted'that by turning Athe iange' 39 slightly inward and tapering the web 38, sharp edges and corners are/eliminated, thus obviating .accidents caused by sharp .edges or corners cutting worlimenworking near the'car or catching in their clothing.

At the nds of the car coupling-devices ,40a are provided, each of which comprises a hollow casing member 41 arranged within the body of theear and secured to one-0f the end portions 260i the member 24 'and to relative draw bar 43 .which at its inner 41 isl preferably provided with a ,springseat 44. The' outer' end.

casing y and movable llongitudinally thereto, is a of this draw bar extends beyond the end walland is provided with a couplin pin 45 Ywhich when the car is being dumpe by the use ot' a retary dumping machine and rotatedinthe 'direct-ion of the arrowy in Fig. 3, isv prevented from bar by a dog 46 which is -pivotally mounted on the end wall 2 above the pin 45, excessive movement of such dog being prevented `by' a bolt 47 or any other suitable means. To cushion the pulling shocks to which a car dropping ont of the draw of this type isfsubjected, a spring 48 ispro'- v vided one end of which is seated against one of the endwall's of the casing member 41 fand the opposite en'd against', the spring seat F44 secured tothe draw bar.

I It will'be apparent t0 art to which this invention appertainsthat many changes may be made in the details those skilled in the of the's'everal parts forming the inventionl without vdeparting from the` spirit-and scope ot'the appended claims. f
